部分（ // document.write（variablejs）;无法使用 ），不会写变量variablejs，但是当我使用方法（ // window.location.href =http：//localhost/test2.php？ad =+ variablejs; Working ），它会写入url并转发传递该变量的页面作为参数。我想要做的是在同一个HTML的主体中打印该变量。
我试图首先初始化变量，然后写入主体，但看起来像该部分不能像全局变量或类似的东西那样访问。请帮忙。
The section (//document.write(variablejs); Not working), won't write the variable "variablejs", but when I use the method (//window.location.href = "http://localhost/test2.php?ad="+ variablejs; Working), it will write the url and forward the page passing the variable as a parameter. What I want to do is print that variable in the body of the same HTML. I tried to initialize first the variable then write into the Body but It looks like that section is not accessible like a global variable or something like that. Please help.
推荐答案
文档加载后，不能使用 document.write document.body.innerText = variablejs; 。但我建议您
Once the document is loaded, you can't use document.write without overwriting everything. You will need to manipulate the DOM, e.g. document.body.innerText=variablejs;. But I'd recommend
var d = document.createElement("div");
d.appendChild(document.createTextNode(variablejs));
document.body.appendChild(d);
